Description

Technical Field

[0001] This utility model relates to the field of door and window processing technology, and in particular to a welding corner treatment device. Background Technology

[0002] Aluminum alloy doors and windows refer to doors and windows made using extruded aluminum alloy profiles for frames, mullions, and sashes. During the processing of aluminum alloy doors and windows, the welded corners at both ends of the frame beams are cut, and then the welded corners are joined together. However, after cutting the welded corners, burrs and rough edges appear at the welded corners, affecting subsequent welding. Currently, this is mainly done manually by grinding both ends, which has low processing efficiency, high labor intensity, and causes problems in production. Utility Model Content

The device is equipped with sector gears, which are symmetrically arranged relative to the central axis. The sector working tooth areas of the two sector gears are staggered by a certain phase angle in the circumferential direction, so that when the geared motor rotates continuously, the two sector gears can alternately mesh with the teeth on both sides of the rack and pinion, thereby driving the rack and pinion to perform horizontal reciprocating motion.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-5 As shown, a weld corner treatment device includes a support mechanism, which includes a frame 11, a support box 12 fixed at the upper end of the frame 11, the upper end of the support box 12 being open and a top plate 13 installed at the upper end, and also includes a reciprocating movement mechanism for reciprocating movement of door and window beam frames, and a grinding mechanism located on both sides of the reciprocating movement mechanism on the support mechanism.

[0025] In this embodiment, the reciprocating mechanism includes a central shaft 21 vertically mounted at the bottom of the support box 12. A reduction motor 23 is connected to the lower end of the central shaft 21. Transmission shafts 25 are mounted on the front and rear sides of the central shaft 21. A main gear 22 is fixed on the central shaft 21 and located on the support box 12. A secondary gear 24 meshing with the main gear 22 is fixed on the transmission shaft 25. A sector gear 26 is mounted on the upper side of the secondary gear 24. The sector gears 26 are symmetrically arranged relative to the central shaft 21, and the sector working tooth areas of the two sector gears 26 are offset by a certain phase angle in the circumferential direction. When the geared motor 23 rotates continuously, the two sector gears 26 can alternately mesh with the teeth on both sides of the rack and pinion 27, thereby driving the rack and pinion 27 to perform horizontal reciprocating motion. The inner side of the support box 12 is provided with sliding seats 28 on both sides of the main gear 22. The rack and pinion 27 is horizontally mounted on the sliding seats 28. The front and rear sides of the rack and pinion 27 are provided with teeth that mesh with the sector gears 26. The upper end of the rack and pinion 27 is provided with a clamping assembly for fixing and limiting the beam frame. The clamping assembly passes through the top plate 13, and a through slot is opened horizontally on the top plate 13. The central shaft 21, transmission shaft 25 are rotatably connected to the support box 12 and the top plate 13. The main gear 22 and the auxiliary gear 24 have the same specifications. The rack and pinion 27 is slidably connected to the sliding seat 28. The reduction motor 23 works to drive the main gear 22 on the central shaft 21 to mesh and rotate with the auxiliary gear 24 on the transmission shaft 25. This causes the sector gears 26 on the two transmission shafts 25 to alternately mesh with the rack and pinion 27, driving the rack and pinion 27 to move back and forth horizontally under the limit of the sliding seat 28. This causes the support frame 29 at the upper end of the rack and pinion 27 to move back and forth as a whole, contacting the grinding mechanisms on both sides.

[0026] The clamping assembly includes a support frame 29 fixed to the upper end of the rack and pinion 27. Left and right helical studs 210 are longitudinally mounted on the support frame 29. Handwheels are fixed to both ends of the left and right helical studs 210, which pass through the support frame 29. Clamping plates 211 are arranged opposite each other on the left and right helical studs 210. Guide posts 212 passing through the support frame 29 are provided on the clamping plates 211. The clamping plates 211 pass through the upper end of the support frame 29. The left and right helical studs 210 are rotatably connected to the support frame 29, and the left and right helical studs 210 are threadedly connected to the clamping plates 211. The guide posts 212 are slidably connected to the support frame 29. When a door or window beam frame is placed on the support frame 29, rotating the left and right helical studs 210 causes them to move relative to the clamping plates 211 under the limitation of the guide posts 212, thus clamping and fixing the beam frame on the support frame 29, facilitating the fixing of the beam frame to the support frame 29.

[0027] In this embodiment: the grinding mechanism includes a mounting frame 31 fixed on the top plate 13. A horizontally arranged sliding column 32 and a horizontal shaft 36 are provided on the mounting frame 31. A sliding frame 33 is arranged opposite to the sliding column 32 and the horizontal shaft 36. A vertical grinding wheel 34 is arranged on the opposite surface of the sliding frame 33. A spring 35 is sleeved on the outer diameter of the sliding column 32 between the sliding frame 33 and the mounting frame 31. A transverse grinding wheel 37 is fixed on the horizontal shaft 36. A damping rod 38 is fixed on the mounting frame 31 above the transverse grinding wheel 37. An upper grinding wheel 39 is rotatably mounted on the lower end of the damping rod 38 via a frame. The upper tangential surface of the transverse grinding wheel 37... The beam frame is tangent to the bottom surface of the beam frame placed on the support frame 29; the sliding frame 33 is slidably connected to the sliding column 32 and the horizontal shaft 36, the vertical grinding wheel 34 is rotatably connected to the sliding frame 33, and the horizontal shaft 36 is rotatably connected to the mounting frame 31, so that when the beam frame moves back and forth with the reciprocating moving mechanism, the weld corners at both ends of the beam frame contact the grinding mechanisms on both sides, so that the spring 35 pushes the sliding frame 33 closer to the middle position, the vertical grinding wheel 34 contacts the two sides of the beam frame, the horizontal grinding wheel 37 contacts the bottom surface of the beam frame, and the damping rod 38 pushes the upper grinding wheel 39 to contact the upper end of the beam frame, so that the weld corners of the beam frame are ground during the movement.

[0028] The working principle and usage process of this utility model are as follows: The door / window beam frame is placed on the support frame 29. Rotating the left and right helical studs 210 causes the clamping plates 211 to move relative to each other under the limiting position of the guide post 212, thus clamping and fixing the beam frame on the support frame 29. Then, the reduction motor 23 operates, driving the main gear 22 on the central shaft 21 to mesh and rotate with the secondary gear 24 on the transmission shaft 25. This causes the sector gears 26 on the two transmission shafts 25 to alternately mesh with the rack and pinion connecting rod 27. The rack and pinion 27 moves horizontally back and forth under the limit of the sliding seat 28, which in turn causes the support frame 29 at the upper end of the rack and pinion 27 to move back and forth as a whole, contacting the grinding mechanisms on both sides. This causes the spring 35 to push the sliding frame 33 towards the middle position, the vertical grinding wheel 34 to contact the two sides of the beam frame, the horizontal grinding wheel 37 to contact the bottom surface of the beam frame, and the damping rod 38 to push the upper grinding wheel 39 to contact the upper end of the beam frame, so that the weld corners of the beam frame are ground during the movement.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
